Don't use files in it to calculate fragmentation, and don't show them in the fragmented files. And use a special color for them in the drive map.
+1 for detecting files that can't be defragmented, don't including them in the fragmentation % and marking it with a special color, or include them it in the fragmentation % count but notify the user that these files are static / system files that can't be moved.
Bump. There's too much users complaining about 30% fragmentation or so after DF defragged because there are SRPs...
+1 to this suggestion.
